Industrial fabric for forming and pressing

Abstract

The object of the present invention is to provide an industrial fabric used for forming and pressing building material which is capable of exhibiting a good water suction property, while at the same time of preventing spots from being generated and bristles from being fallen out even if it is repeatedly used for forming and pressing building material and a strong washing shower is applied thereto. The present invention provides a industrial fabric used for a forming process and a pressing process comprises one-layer fabric including warps and wefts constituting the fabric at least a part of which is intertwined by small-diameter raw yarns and fibers of the small-diameter raw yarns are crossed by jetting water in a columnar stream or a spray stream thereto, or multi-layer fabric including warps and wefts constituting an upper surface side layer at least a part of which is intertwined by small-diameter raw yarns and fibers of the small-diameter raw yarns are crossed by jetting water in a columnar stream or a spray stream thereto.

1 . An industrial fabric used for forming process and pressing process comprises one-layer fabric including warps and wefts constituting the fabric at least a part of which is woven by yarns consisting of bundled small-diameter raw yarns and fibers of the small-diameter raw yarns are crossed by jetting water in a columnar stream or a spray stream thereto, or multi-layer fabric including warps and wefts constituting an upper surface side layer at least a part of which is woven by yarns consisting of bundled small-diameter raw yarns and fibers of the small-diameter raw yarns are crossed by jetting water in a columnar stream or a spray stream thereto. 
     
     
         2 . The industrial fabric used for forming process and pressing process according to  claim 1 , wherein the bundled small-diameter raw yarns are selected from a group consisting of an open-spun yarn, a multifilament, a Taslan processed yarn, a monofilament twine, a mole yarn, a filament processed yarn, a yarn in which a spun yarn is wound on a core line of a monofilament, a yarn in which a multifilament is wound on a core line of a monofilament, and a yarn in which at least two kinds of these yarns are co-twined. 
     
     
         3 . The industrial fabric used for forming process and pressing process according to  claim 1 , wherein said warps constituting the fabric is a monofilament and no less than half of said upper wefts consist of yarns of the bundled small-diameter raw yarns to form a structure of a single warp-double weft type, or of a double warp-double weft type in which the upper wefts and lower wefts constituting a lower surface side layer are laminated. 
     
     
         4 . The industrial fabric used for forming process and pressing process according to  claim 1 , wherein said warps constituting the fabric is a monofilament and no less than half of said upper wefts consist of yarns of the bundles small-diameter raw yarns to form a structure of a single warp-triple weft type in which the upper wefts and middle wefts constituting a middle layer, and lower wefts are laminated. 
     
     
         5 . The industrial fabric used for forming process and pressing process according to  claim 4 , wherein said warp constituting the fabric is a monofilament and no less than half of said upper wefts consist of yarns of the bundled small-diameter raw yarns, and at least a part of either of said middle wefts or said lower wefts consist of yarns of the bundled small-diameter raw yarns to form a structure of a single warp-triple weft type in which the upper wefts, the middle wefts, and the lower wefts are laminated. 
     
     
         6 . The industrial fabric used for forming process and pressing process according to  claim 1 , wherein said warp constituting the fabric is a monofilament and no less than half of said upper wefts consist of yarns of the bundled small-diameter raw yarns to form a structure of a single warp-single weft type. 
     
     
         7 . The industrial fabric used for forming process and pressing process according to  claim 1 , wherein at least a part of the warps constituting the fabric consists of yarns of the bundled small-diameter raw yarns.
